IO-Errors
#1 -- Total I/O error count for a path. The maximum
value that can be displayed is 2
32 - 1
(4294967295). If the total I/O error count reaches
the maximum value, it is reset, and the count is re-
started from 0.
To reset the IO-Errors value to 0, execute the
dlnkmgr command's clear operation. Executing the
clear operation also clears the number of I/O
operations (IO-Count) to 0.
For details on the clear operation, see
